Thereby the logic of the safety output of Unit B is a b. (An of inputs a and b is output.) To set the safety outputs of the subsequent Unit in the state, its logical connection preset switch must be set to (enable) and the HIGH state signal must be input to T41 of the subsequent unit.

Using Auto Switching: For the safety output to go to the state, both channels 1 and 2 of safety input A must be in the state, channels 1 and 2 of safety input B must be in the state. Using Manual Switching: For the safety output to go to the state when safety input A is activated, both channels 1 and 2 of safety input A must be in the state (for maintenance mode). For the safety output to go to the state when safety input B is activated, both channels 1 and 2 of safety input B must be in the state (for normal operating mode). Wiring Connect the power supply plus (24 VDC) to the A1 terminal. Connect the power supply minus (GND) to the A2 terminal.

Otherwise the safety outputs cannot be in the state. For the safety output to go to the state, the signal input to T32 must change from the state to the state, and then to the state. Otherwise the safety outputs cannot be in the state. A logical connection means that one Unit (Unit A) outputs a safety signal a to a subsequent Unit (Unit B) and Unit B calculates the logical of a and safety signal b. In the example shown at the right, the logical connection results in a safety output of a b for Unit B. Connect L1 of Unit A and T41 of Unit B to the power supply negative terminal (GND) of Unit A and T42 of Unit B. For the safety output to go to the state in the subsequent Unit, its logical connection preset switch must be set to (enabled) and the HIGH state signal must be input to T41 of the subsequent Unit. When manual switching is selected, the SPST-NO/ SPST-NC input enables the input of either safety input A or safety input B. The relationship of the safety input enable state and the mode selector input is as follows: M1 =, M2 = : Safety input B is enabled (normal operating mode) M1 =, M2 = : Safety input A is enabled (maintenance mode) Selects the mode for the failure detecting (cross fault detecting) function for the safety inputs of G9SX-GS@ corresponding to the connection of the cross fault detection input.

When Y1 is open, short-circuit failures are detected between safety inputs T11-T12 and T21-T22. When Y2 is open, short-circuit failures are detected between safety inputs T61-T62 and T71-T72. When a cross fault is detected, the following will occur. 1. The safety outputs and logical output will be locked out. 2. The LED error will light. 3. The error output (auxiliary output) will turn. When a safety sensor, such as a Safety Light Curtain, is connected to safety input A, connect Y1 to 24 V. When a safety sensor is connected to safety input B, connect Y2 to 24 V. If they are not connected to 24 V, the G9SX-GS@ will detect an error.

The PL must be evaluated in an actual application by the customer after confirming the usage conditions. Application Overview 2 1. Normal operating mode (When the mode M1 of the G9SX-GS is turned.) Normal operating mode (M1 =, M2 = ) is selected on the selector switch S7. The enabling switch S3 and S4 for detecting the conveyor cart position are disabled. 1-1.When the emergency stop switch S1 is pressed. The power supply to the motor M1 and M2 is turned immediately when the emergency stop switch S1 is pressed. The power supply to the motor M1 is kept until the reset switch S2 is pressed while the emergency stop switch S1 is released. The power supply to the motor M2 is kept until the reset switch S2 and S8 are pressed while the guard is closed and the emergency stop switch S1 is released. 1-2.When the guard is opened (the emergency stop switch S1 is released). The power supply to the motor M2 is turned immediately when the S5 and S6 detect that the guard is opened. (The power supply to the motor M1 is kept.) The power supply to the motor M2 is kept until the guard is closed and the reset switch S8 is pressed. 2. Maintenance mode (When the mode M2 of the G9SX-GS is turned.) Maintenance mode (M1 =, M2 = ) is selected on the selector switch S7. The S5 to detect the opening and closing of the guard is disabled. 2-1.When the emergency stop switch S1 is pressed. The power supply to the motor M1 and M2 is turned immediately when the emergency stop switch S1 is pressed. The power supply to the motor M1 is kept until the reset switch S2 is pressed while the emergency stop switch S1 is released. The power supply to the motor M2 is kept until the reset switch S2 and S8 are pressed while the conveyor cart is at the safety position and safety limit switch S3 and S4 are turned and the emergency stop switch S1 is released. 2-2.When the conveyor cart moves away from its safe position (the emergency stop switch S1 is released). The power supply to the motor M2 is turned after the conveyor cart moving away from the safety position and the safety limit switch S3 and S4 being turned. (The power supply to the motor M1 is kept.) The power supply to the motor M2 is kept until the reset switch S8 is pressed after the conveyor cart returning to the safety position and the safety limit switch S3 and S4 being turned. 39

(2) Use the selector switch to change to maintenance mode when the conveyor cart is at the safety position. (3) The operator opens the guard and performs maintenance. (4) When Safety Limit Switch S3 and Limit Switch S4 are turned in maintenance mode, Unit 2 stops. (5) After the guard is closed and the operating mode is switched to normal operating mode, restart Unit 2. (6) When the guard is opened during normal operating mode, Unit 2 stops. (7) Close the guard and restart Unit 2. (8) When the operating mode is switched to maintenance mode while Safety Limit Switch S3 and Limit Switch S4 are turned, Unit 2 stops. (9) Switch to normal operating mode, and when the guard is closed, restart Unit 2. (10) Emergency stop switch pressed: All units stop. Note: 1. In this example, press reset switch S2, confirm that Unit 1 has started operating, then press reset switch S8. 2. To use the set value of the mode selector for control, use external output UA for control and external output UB for the operator's indication. In this case, disable the diagnostic check of the external output UA. 41
